8' Claims.

This invention relates to orifice-provided elements.

More particularly, the invention comprises a hollow body provided withend openings and further provided with a lateralopening, a set oforilice-provided elements, the orifices of the respective elements beingof different predetermined cross-sectional areas, and. retaining meansfor the selected orifice-provided element whereby upon insertion throughthe lateral opening and suitable positioning of the same within thehollow body, the orifice of the element effectually controls the fiow orrate of flow of fluid through the va ve.

Preferably, the orifice-provided element and its retaining means whenarranged in position are concealed from tampering, to thus precludedisturbance of the same by unauthorized persons. Advantageously, suchpurpose is carried out by providing the lateral opening with a closurecap, which may serve also to seal the lateral opening against fluidleakage.

The retaining means, preferably, is provided with effective facescoacting with the orifice-provided element, which faces are contoured toengage inner face portions of the hollow body in substantialfluid-sealed relation therewith. The retaining means is advantageouslyformed to have retaining portions spaced from one another,

to provide a clearance of predetermined dimension, such clearanceserving as a slot, each orilice-provided element having a thicknesscorresponding to such predetermined dimension to enable the element tobe inserted in such slot and effectively held therein, the retainingportions respectively having an outer contour, thefaces of whichsubstantially correspond to and engage abutting inner face portions ofthe hollow body, to preclude or minimize leakage of fluid thereat.

In the preferred forms of the invention, each orifice-provided elementis further provided with an aperture, which conveniently is aperforation, at a portion thereof accessible within the lateral openingof the valve body, whereby upon removal of the closure cap, theorifice-provided element may be readily withdrawn by insertion of asuitable tool into such aperture and the application of force.

In the most preferred forms of the invention, the retaining memberembodies a body portion to which the stated spaced retaining portionsare integral or otherwise rigidly secured, the body portionbeingprovided with a slot communicating with the slot of predeterminedclearance, ,each orifice-provided element having an extension arrangedto be inserted through the slot of the body portion, the hollow bodybeing provided at its interior with annular formations, convenientlyformed integral with the material of the valve, body, the material ofthe valve body being extended to partially fill the virtual bottom ofthe lateral opening. Such formations result effectively as or in thenature of a boss; these formations are spaced from one another withinthe bore of the hollow body and provide a slotted opening 10 accessiblethrough the lateral opening and serves for the reception of theassembled orifice-provided element and its retaining means.-

Further features and objects of the invention will be more fullyunderstood from the following detail description and the accompanyingdrawing, in which Fig. 1 is a central vertical section of an orificevalve embodying my invention; this view also illustrates the assembly ofthe orifice valve with p p Fig. 2 is a top plan view of Fig. 1, with theclosure cap removed;

Fig. 3 is a vertical sectional view, on line 33- of Fig. 1;

Fig. 4 is a detail perspective view of a retaining member for retainingan orifice-provided ele ment;

Fig. 5 is a detail perspective view of one size of orifice-providedelement;

Fig. 6 is a detail perspective view of another size of orifice-providedelement; and

Fig. 7 is a detail perspective view of an orificeprovided element whichis imperforate, that is, of nil size, serving as a shut off valve.

Referring to the drawing, the body ill of the valve is of any suitableconstruction, embodying end openings Ii, l2 and alateral opening l3.Usually, the end openings ll, l2 are in alignment with one another andthe lateral opening I3 is- 40 normal to the end openings. Tubes or pipesI4, l5 are shown connected to the end openings II,

I2, respectively. Any suitable form of connec-' tion may be employed. Inthe illustrated embodiment such connection is had by a sweated 45 joint,that is to say, the inner faces of the end openings ll l2 are smooth anddimensioned with respect to the ends of the tubes or pipes l4, l5 toprovide for capillary or surface flow of a suitable bonding medium, suchas solder, which is 50 usually applied after heating the respectiveoverlapping ortelescoped end portions, the solder upon coolingcongealing to form a fluid tight joint of suflicient rigidity. Theinvention finds wideapplication in hot water heating systems andparticularly with the use of copper piping. Accordingly, in such use,

Suitable orifice-provided means is disposed' within the hollow body ofthe valve through its lateral opening l3 for eifectually controlling thefiow of fluid through the hollow body. Advantageously, theorifice-provided element is in the form of a plate which is providedwith an orifice of any predetermined or desired cross-sectional area. Inthe commercial practice of the invention, a set of plates is furnishedhaving respectively orifices of diiferent sizes", for selection of theparticular plate having the desired size of orifice, to eifect thedesired regulation of the fluid fiow.

To accomplish such and other purposes, I prefer a retaining member I6comprising essentially the retaining portions I60, I61; spaced from oneanother to provide a slot l 6b of predetermined clearance, to slidinglyand frictionally receive and retain the selected orifice-provided plate,having an effective thickness corresponding to the dimension of thepredetermined clearance.

A set of orifice-provided plates ll, [8, I9, etc., is illustrated inFigs. 5, 6 and 7. The orifice of the element I1 is indicated at Ila, seeFig. 5, and shown circular in configuration and of a diameter ofpredetermined size. The orifice of the element I8 is indicated at l8a,see Fig. 6, which is also shown as circular in configuration. Asillustrated, the size of the orifice l8a is less than that of theorifice Ho. The element I9 is shown devoid of'an'orifice, see Fig. '7,in which instance,

the fiuid fiow is nil, that is to say, serving as a shut off valve,applicable under certain circumstances.

The respective spaced retaining portions "5a, [6a, are provided withopenings l8e of an effective cross-sectional area greater than thecross-sectional area of the maximum orifice of the set oforifice-provided elements, to aiford eifective control of the fluid flowby the orifice of the selected orifice-provided element.

For effectiveness of assembly of the selected orifice-provided elementand its retaining means is, and the ready insertion and the readywithdrawal of the assembly through the lateral opening I3, I providewithin the longitudinal bore of the hollow body annular formations 20,20, advantageously integral with the material of the hollow body, suchformations including extensions 20a, 20a, see Fig. 2, at the region ofintersection of the lateral opening with the longitudinal bore of thehollow body. Such formations result in the provision of the slottedopening 2 I, see Fig. 2, for the reception of the assembled selectedorificeprovided. element and its retaining means. 'By dimensioning andcontouring the retaining means It, in particular its portions Mic, withrespect to the slotted opening 2| for making a tight frictional fittherein, the leakage of fluid between the mutually engaging faces isminimized and, if desired, substantially precluded. Nicety of frictionalfit in contour and dimension is also made with respect to the mutuallyengaging faces between the lateral i. e. circular face of the bodyportion I60 of the retaining means 3 relative to the inner face of thebore of the lateral opening l3, to minimize or preclude possible leakagebetween the mutually engaging faces is'had by the provision of a closurecap 22, which may be provided with a gasket 23, see Figs. 1 and 3. Thegasket 23 is preferably of annular configuration, as appears more fullyhereinafter.

By the use of the closure cap 22 it serves also to conceal theorifice-selected element and normally precludes tampering byunauthorized persons.

For the ready insertion and withdrawal of the assembly of the selectedorifice-provided element and its retaining means l6, eachorifice-provided element, say I I, is provided with an upper extensionIlb having an aperture or other recess Ho, and combined therewith Iprovide the body Hie of the retaining means 5 with a centrally locatedslot lfid through which the extension I 7b is passed. Thus, suchextension I'lb serves as a finger piece for effecting the insertion ofthe stated combined assembly, and by means of the aperture l 10 thecombined assembly may be readily grasped and removed by means of asimple tool.

Such preferred form of the invention further embodies the advantage ofaffording pressure upon the orifice-provided element by engagement ofits upper extension llb by the closure cap 22 upon tightening of thelatter, and coincident with such purpose I provide the lower and lateralarcuate face, see lld, Fig. 5, of the orifice-provided.

element I! in this instance, to have a contour substantially preciselycoincidental with the contour of the inner face of the bore of thehollow body It], as is indicated in Fig. 3. Corresponding parts of theremaining elements of the set of orifice-provided elements aredesignated by corresponding letter-sufiix reference characters, andfunction in similar manner.

The closure cap may be applied in any suitable manner, as by matingscrew-threading as indicated, or by a friction fit cap, etc.

The element [9, see Fig. '7, conforming in out line to an orificeprovided element, such as ll, [8, etc., but not embodying an orificeopening, may be employed for the purpose of complete restriction, thatis, to shut-off the flow of the fluid.

My invention is applicable for all suitable systems providing for theflow of fluids of all character, including liquid, gas, and fiowablesolids and the like; as specific illustrations, I cite hot water heatingsystems, water piping systems, refrigerating systems, domestic gas andother gas piping systems.

The advantages of my system are apparent from the herein disclosure. Therequirement of individual orifice provided elements in sets respectivelyhaving different diameter or other dimensioned orifice openings, effectsin practice substantial freedom from tampering by unauthorized persons.The absence of a valve stem or equivalent part accessible exteriorly ofthe valve body attains the object of concealment, tending towarddiscouragement of tampering. A look for the cap operated by key orotherwise may be employed if desired.

Whereas I have described my invention by reference to specific formsthereof, it will be understood that many changes and modifications maybe made without departing from the spirit of the invention.
